M23 rebels advance as tension mounts between DR Congo and Rwanda

M23 rebels in the Democratic Republic of Congo, who defected from the Congolese army in April, have entered the city of Goma in North Kivu province. Kinshasa accuses Rwanda of using the M23 army as a proxy force to destabilise the region and gain control of its mineral resources. Tensions are mounting between the two countries, threatening to worsen the humanitarian situation in eastern Congo.
